Paragraph 1: Encapsulated transformer with a NEMA 3R enclosure delivers rugged weather resistance, reducing environmental ingress and unplanned downtime. This protection translates to longer service life in outdoor and challenging indoor installations. Paragraph 2: The S38D11S07 uses Frame 178 and a weight of 136 lb for secure mounting in standard electrical rooms. The solid mechanical design simplifies retrofits and ensures vibration resistance in demanding environments. Paragraph 3: It operates at 60 Hz with a 380 V primary and 120/240 V secondary, supporting straightforward power conditioning for common industrial loads. Tap options at +2.5% and -2.5% provide precise voltage regulation to maintain equipment performance. Paragraph 4: Rated at 7.5 VA with a 115 °C rise, it supports reliable operation under moderate overload and higher ambient temperatures. The combination of performance and protection reduces energy waste and prolongs lifetime of downstream equipment. Paragraph 5: CSA Certified and UL Listed certifications, along with NEMA 3R, reinforce regulatory compliance and safety for panel builders and OEMs. A one-year warranty (or 18 months from shipment) provides peace of mind and total-cost-of-ownership benefits.
